摘　　要：根据八洋河料场地质和施工条件,利用预裂爆破成缝机理,计算各爆破参数理论数值。通过现场试验,最终确定八洋河料场大孔径宽孔距预裂爆破参数,半孔率达到90%以上,提高了工程质量,降低了工程造价,取得了较好的经济效益。In accordance with Bayanghe stock yard construction and geological conditions, making use of Pre-splitting blasting crack-theoretic, theoretical values of pre-splitting blasting parameters are calculated. Through field test, finally Large Aperture Wide space pre-splitting blasting parameters of Bayangbe stock yard are ascertained, half-cast factor is above 90%, improving the quality of construction projects, lowering the construction costs, getting a better economic efficiency.
